摘要： A multi-bypass pulse tube refrigerator comprising a pressure wave generator, a regenerator, a heat exchanger of cold ends (cold finger), a pulse tube, an orifice means and a reservoir volume, connecting in serial. Matrix material made of material of high heat capacity is packed in the regenerator. Rectifying means are arranged at the ends of the pulse tube. The outlet of the pressure wave generator is connected with the hot end of the regenerator. The connection between the cold ends of the regenerator and the pulse tube forms the heat exchanger of cold ends. The reservoir volume is connected with the hot end of the pulse tube through the orifice means. Resistance means are properly arranged in the pulse tube, so as to for gas to pass through the pulse tube uniformly and smoothly. At least one bypass with a throttling means is provided to connect the regenerator and the pulse tube. The refrigerator provided by the invention has a lower refrigeration temperature, high refrigeration capacity and improved refrigeration efficiency.
